Re: The United Illuminating Company’s Notice of Exempt Modification Pursuant to R.C.S.A. § 16-50j-58 to Existing Energy Facility Site between Pequonnock Substation in Bridgeport and Sasco Creek Substation in Westport (“Notice of Exempt Modification”)

Dear Vice Chairman Murphy:

Pursuant to Regulations of Connecticut State Agencies (“R.C.S.A.”) §16-50j-58, The United Illuminating Company (“UI” ) hereby notifies the Connecticut Siting Council (the “Council”) of its intent to make exempt modifications (the “Project”) to its transmission line along the Metro-North Railroad corridor (“Railroad Corridor”) from Pequonnock Substation in Bridgeport to Ash Creek Substation in Fairfield interconnecting with The Connecticut Light and Power Company d//b/a Eversource Energy’s (“Eversource”) Sasco Creek Substation in Westport (“Facility” or “Energy Facility”). The $625 filing fees, along with 2 copies of this Notice of Exempt Modification, are enclosed herewith.

Existing Energy Facility

The Facility begins at Pequonnock Substation in the City of Bridgeport at 41°10′20"𝑁𝑁 and Λ 73°11′06"𝑊𝑊 and proceeds in a westerly direction approximately 3.75 miles along the Railroad Corridor to Ash Creek Substation at 41°09′23"𝑁𝑁 and Λ 73°14′03"𝑊𝑊 continuing westerly an additional 5.27 miles interconnecting with Eversource’s Sasco Creek Substation at 41°07′27"𝑁𝑁 and Λ 73°18′29"𝑊𝑊:

The existing Facility consists of a FOCAS Skylite 12 fiber Optical Ground Wire (OPGW) completed in 1994. This Facility provides communications and lightning protection for UI’s and Eversource’s 115 kV transmission lines and are installed on bonnet extensions on top of the Metro-North catenary system from Pequonnock Substation to Metro-North Catenary # 737 (41°10'20.58"N and Λ 73°11'6.62"W). At this point the Facility is erected on single circuit monopole structures installed within the Railroad Corridor continuing westerly to Eversource’s Sasco Creek Substation.

Proposed Modifications UI is proposing to replace the existing FOCAS Skylite 12 OPGW (See Attachment B for existing OPGW Cut Sheet) with a new Prysmian 64K78s 48 fiber OPGW (See Attachment C for proposed OPGW Cut Sheet). This replacement is due to fiber communication issues associated with loss of signal, fiber breaks, lack of spare fibers and intermittent signal failure. This OPGW is critical for the reliable operation of UI’s and Eversource’s transmission system. These fibers are used to monitor and control the 1130, 1430, and 91001 Lines primary relaying, UI’s and Eversource’s Jungle MUX, UI’s Corporate Network, UI’s Supervisory Control and Data Acquisition Network, Advanced Metering Infrastructure communications, and Ash Creek Substation’s telecommunications system. As the Project relates solely to improving system maintenance, the modifications will not impact the existing Facility’s structural capability or impact electric and magnetic fields or noise levels.

OPGW Inspection – December 8, 2018

Compliance with R.C.S.A. § 16-50j-57(b) Pursuant to R.C.S.A. §16-50j-57(b), the Project does not constitute a modification to an existing facility that may have a substantial adverse environmental effect and are exempt from the requirement to obtain a certificate pursuant to Section 16-50k of the Connecticut General Statutes. Specifically, consistent with R.C.S.A. § 16-50j-57(b), the proposed changes to the existing site do not:

(A) Extend the boundaries of the site beyond the existing right-of-way; (B) Increase the height of existing associated equipment; (C) Increase noise levels along the right-of-way by six decibels or more, or to levels that

exceed state and local criteria; (D) Impact electric and magnetic field levels along the right-of-way in a manner that is

inconsistent with the Council’s Best Management practices for Electric and Magnetic Fields;

(E) Cause a significant adverse change or alteration in the physical or environmental characteristics of the right-of-way; or

(F) Impair the structural integrity of the facility, as determined in a certification provided by a professional engineer licensed in Connecticut, where applicable.

The Project would not have a substantial adverse environmental effect or cause a significant adverse change or alteration in the physical or environmental characteristics because:

(A) The Project would be located within the transmission line’s existing right-of-way; the right-of-way area would not be expanded;

(B) The equipment would be no taller than existing equipment within the right-of-way; (C) There would be no change to the existing television or radio interference resulting

from the modifications of the transmission line; (D) Sound-pressure levels at all points along properties lines would continue to meet

state regulations set out in R.C.S.A. §§ 22a-69-1 et seq.; (E) The project work would not affect water resource areas. (F) UI’s review of the Connecticut Department of Energy and Environmental

Protection’s Natural Diversity Data Base did not identify any state-listed endangered, threatened, or special concern species in the vicinity of the Project; and

(G) Electric and Magnetic field levels along the transmission line will not change as a result of the Project.

UI intends to initiate the Project on or after the Council’s acknowledgement that the proposed activities are exempt.

Please do not hesitate to contact me at 203-988-9746 should you have any questions regarding this notice.

Very truly yours,

James M. Yeske Jr. Manager – Electric Capital Line Projects The United Illuminating Company
